I was once faced with similar issue. Did you try increasing the rgw

As Tom stated, RBD cache only works if your client is using librbd (KVM
clients for instance).
Using the kernel RBD client, one of the parameter you can tune to optimize
sequential read is increasing /sys/class/block/rbd4/queue/read_ahead_kb
